I'm a pocket fan too Janie - BumGenius and GreenKids are my faves - but that's probably because they're both one size fits all. I love the BumGenius all-in-ones, but because they're not one size fits all, they're not as economical. The stash that I'm using for Jambin at the moment should fit him until he's toilet trained, as they're pretty much all OSFA.
